Atik 383L+ utilizing the kodak 8300 series sensor at 500 grams weighs no more than my 40d

although most of au and usa know very little about these camera's i think they arnt too bad at all. and priced to compleat should put up some good competition.
also in they have just released a OAG and slim line filter wheel.
